Stakeholder-based decision support model for selection of alternative water sources-A path towards sustainable industrial future in Vietnam

Journal article (2022) - A. Bhatta, Truong Minh Le, Truong Minh Le, Koen Wetser, Katarzyna Kujawa-Roeleveld, Huub H M Rijnaarts

The combined effect of climate change, rapid industrialisation and traditional water use has created freshwater stress situations in industrial delta regions. Alternative Water Sources (AWSs) offer opportunities to mitigate the freshwater stress issue and, thus, contribute to a s ...

Wastewater paradigms in India and the Netherlands

Journal article (2021) - Sumit Vij, Sumit Vij, Eddy Moors, Eddy Moors, Katarzyna Kujawa-Roeleveld, R.E.F. Lindeboom, Tanya Singh, M.K. de Kreuk

Freshwater scarcity has increased in the cities of the global South due to rapid urban agglomeration and changing climate. Alternative water resources such as treated wastewater can play a significant role to reduce the water supply-demand gap. In the recent past, wastewater has been used solely for irrigation and other allied agriculture purposes, with limited focus on reuse for other purposes within the cities. Despite the progress in wastewater treatment technology and various policy frameworks, in low income and lower-middle-income countries, limited progress has been made. Through this article, we compare three aspects, representing the wastewater paradigms in India and the Netherlands. The three elements are 1) framing, 2) policy goals, and 3) technical and financial instruments. Using policy document analysis and interviews, we compare water and related policies prepared in India and the Netherlands. We found that the wastewater paradigms have evolved in the two countries. In India, the wastewater paradigms have realized paradigm changes from ‘water resource to meet a basic human need’ to ‘water as an engine of economic growth’ and then to ‘water scarcity and beautification of cities’. In the case of the Netherlands, the wastewater paradigms have changed from an emphasis on ‘public health and environmental concerns’ to the ‘circular economy of wastewater’. Although the Netherlands has to still meet the water quality targets of the European Water Directive Framework with regards to micropollutants, the country has made significant progress towards wastewater treatment and reuse in the last four decades. On the contrary, the Indian wastewater policy domain has room for improvement in terms of designing appropriate financial instruments and governance strategies to increase the urban wastewater treatment capacity and reuse. This article concludes that the use of the concept of wastewater paradigm is useful to show the progress and challenges in the two countries.

Possibilities for improving the Urban Metabolism in Bucaramanga in a comparison study with Amsterdam

Master thesis (2019) - S. Hoeke, Katarzyna Kujawa-Roeleveld, Wei-Shan Chen

This research provides an analysis and overview of the tools available to a municipal government to design a governance strategy aimed to enhance the circularity of an urban system. This analysis is performed by means of sources found in literature and by comparing two case studies: Bucaramanga and Amsterdam. Bucaramanga is chosen due to its current solid waste challenge as a result of the problems caused by the local sanitary landfilling site. Amsterdam, on the other hand, is taken as a best practice. From the analysis of Amsterdam lessons are derived that are considered valuable for other urban areas aiming for a higher level of circularity. Additionally, a framework is provided to assess and quantify the circularity of an urban system. By means of the selected circularity indicators in this framework, the level of circularity of the two case studies could be quantified and compared. It is argued that this framework provides a valuable first assessment of circularity and is suitable for both data-rich and data-poor urban areas. It is concluded that the current urban metabolism in terms of municipal solid waste management of Bucaramanga is highly linear. Furthermore, the objectives and activities as currently formulated by the municipal government of Bucaramanga are considered to be too general to tackle this challenge effectively. Lessons obtained from Amsterdam and derived from the performed scenario analysis and governance research are provided and are argued to be valuable to Bucaramanga in constructing a governance strategy towards circularity. Generally, this research provides a number of tools and recommendations that can be used for the analysis and enhancement of circularity in MSW management. By doing this is it contributes to reducing the risk on environmental and public harm as a result of inadequate MSW management. Additionally, the opportunities and limitations of transitions towards a circular economy are explored, providing lessons that can be used by urban systems interested in this transition.
